I have a 72 from Ca with sorta the same deal. Looks like an earlier HD frame with a metal tag rivited to neck which is now gone except for rivets and very small piece of metal. No stamped vin and the pogo seat post makes me say 70 down hd frame. Title says 72Harley Davidson CA50345, engine# is correct which specs out as 72 FL. I am afraid of getting a title in TX as they would give me some bs assembled title as well. I traded my son my softail for it so I will just have him keep registering it in CA for me and I will reg the softail for him. Interested to see how this works out for you.
